ABSTRACT
OBJECTIVES:
Hospital point prevalence surveys (PPS) are shown to help identifying determinants for inappropriate antimicrobial therapy (AMT) and create feedback opportunities to optimize AMT.METHODS:
PPS were performed at the AZNikolaas hospital, on four wards with high consumption rates of three alert antibiotics (AB) to judge their appropriateness. The impact of a multidisciplinary interaction between a medical microbiologist, a clinical pharmacist and the prescriber on inappropriate AMT, hospital costs and intravenous AMT days, was analyzed.RESULTS:
During this survey, 7,39% of hospitalized patients in the selected wards received one or more of three alert antibiotics. Out of 78 prescriptions, 35.90% were judged appropriate, 39.74% inappropriate and 24.36% had insufficient data for judgment. Only the oncology ward was associated with more frequent appropriate use of alert AB. In case of an unknown infection focus or a catheter-related infection, the relative risk of inappropriate use was the highest. Multidisciplinary interaction improved inappropriate AMT in 59% of cases. It resulted in a 2478 healthcare AMT cost saving and a reduction of 30 intravenous AMT days.CONCLUSIONS:
This survey shows high consumption rates and a high rate of inappropriate use of three alert AB in the observed wards. It revealed the lack of a local guideline concerning treatment of neutropenic fever of unknown origin and the need for more diagnostic information in electronical medical records. The survey demonstrated that direct feedback on inappropriate AMT to clinicians can be of added value, cost-saving and reducing length of intravenous AMT days. However, more studies are needed to confirm this.Key words
